Is it ethical to refuse accepting Syria war immigrants?

don't confuse migrants (who have a choice) and refugees (who don't have a choice re leaving e.g. due to their country being at war); re refugees, not just unethical to refuse, but also in many cases illegal (only sharing wikipedia link as it's very basic/ accessible viz legalese of full refugee related int'l law): https://en.wikipedia.org/wiki/Convention_Relating_to_the_Status_of_Refugees
